python-3.x - Ping 操作在 pycharm 中运行良好，但在 jupyter notebook 中无法运行

Question

我有一段代码将使用代码中提到的特定 IP 地址 ping 2 台服务器，它会以漂亮表的形式列出 ping 所花费的时间。当我在 pycharm 中执行相同的代码时，它工作正常。但是，如果我在 jupyter notebook 中执行它，代码不会被执行，因此 ping 的时间不会在漂亮的表中更新。任何人都可以告诉我问题是什么？

这是我在控制台中得到的输出： Table For Ping Timings: +-----------------+---------------- -----+ | 8.8.8.8 的时间 | 时间为 13.32.32。0 | +------------------+----------+ | 32 | 236 | | 19 | 234 | | 46 | 227 | | 45 | 241 | | 29 | 239 | | 33 | 234 | | 21 | 230 | | 22 | 226 | | 26 | 235 | | 26 | 235 | | 24 | 238 | | 20 | 243 | | 26 | 234 | | 26 | 233 | | 26 | 238 | | 27 | 232 | | 123 | 240 | | 29 | 233 | | 39 | 241 | | 29 | 第453章 | 26 | 234 | | 43 | 236 | | 30 | 255 | | 20 | 233 | | 35 | 238 | | 21 | 245 | | 36 | 232 | | 47 | 262 | | 23 | 242 | | 28 | 243 | | 25 | 246 | | 24 | 232 | | 34 | 235 | | 55 | 237 | | 37 | 227 | | 36 | 240 | | 21 | 255 | | 27 | 227 | | 33 | 235 | | 38 | 235 | | 25 | 251 | | 28 | 249 | | 19 | 234 | | 27 | 233 | | 27 | 237 | | 40 | 244 | | 24 | 232 | | 20 | 229 | | 27 | 235 | | 32 | 230 | +------------------+----------+ | | 20 | 229 | | 27 | 235 | | 32 | 230 | +------------------+----------+ | | 20 | 229 | | 27 | 235 | | 32 | 230 | +------------------+----------+

这是我在 pycharm 中得到的输出
